How to fix Deque not working
Deque is a digital accessibility company. It provides the axe engine and tools for testing websites and apps for accessibility, along with monitoring, audits and training. Developers and accessibility teams use its tools. Find your symptom below. Most problems come from a sign-in, a browser extension or testing set-up, a connection to a site under test, or the platform itself. Check the status page before you run a large scan on a live site.
Jump to what you are seeing
- Website Down
- Login Failed
- axe DevTools Error
- Deque University Down
- API Connection Error

- axe Auditor Down
Website Down
The Deque website does not load for you.
- Open the page in a private window and on another network.
- Check status.deque.com for an active incident.
- If only your network is affected, ask IT to check the firewall.
Login Failed
Sign-in is refused.
- If the message says the password is wrong, reset it and check spam.
- Use the sign-in route your organisation set up, such as single sign-on.
- Try a private window to rule out an old session.
axe DevTools Error
The browser extension does not run a check, or it reports an error.
- Update the extension in your browser, and reload the page you are testing.
- Check the page is fully loaded before you start a scan, and that it does not need a sign-in you have not entered.
- Check status.deque.com, and report the error text and the page address if it stays broken.
Deque University Down
The training course pages do not load, or your progress does not save.
- Reload in a private window, and check you are signed in to the right account.
- Check your connection, and let the course finish saving before you leave.
- Check status.deque.com, and tell your training administrator the course name and the time.
API Connection Error
Calls to the Deque API fail or return an error.
- Check the status code. An access error usually means the key is wrong, too many calls means you should slow down, and a server error means a service-side problem.
- Confirm the key has not been revoked and is for the right account.
- Retry with a growing delay, and check status.deque.com if several calls fail together.
axe Monitor Down
Scheduled accessibility monitoring does not run, or its results do not show.
- Check the monitor is switched on, and that its address and schedule are correct.
- Check the site being monitored is reachable from outside its network.
- Check status.deque.com, then run one monitor by hand to check the result.
axe Auditor Down
A guided accessibility audit does not load, or it does not save its results.
- Reload in a private window, and save your findings before you close the audit.
- Check your connection, and the access you have to the project.
- Check status.deque.com, and report the audit name and the time to your project lead.
Still not working?
Contact your organisation's Deque administrator or project lead first, since they manage licences and projects. For a platform-wide problem, contact Deque support through the help option on the Deque website. Have your organisation name, the tool or product name, the page address under test, the exact error text, and the time with your time zone. Never send passwords, tokens or confidential website content in a support message. Live incident updates are on status.deque.com.
Most accessibility-tool problems come from a browser extension, a sign-in or a page that is not fully loaded, and they usually clear once that is checked. The status page shows live incidents, so you can see whether the problem is on Deque's side.
